arduino rc switch demo simple example or advanced example

Hi all, Cannot get either of the above examples to work. Nothing shows up on my serial monitor. I am trying to decode a 433mhz remote control of a mains outlet switch.
The receiver module I am using is a rxn3-b. I am thinking now that this is not a suitable receiver for the arduino example. I see that on e-bay there are many types of receivers and transmitters.
Can anybody vouch for a receiver module that actually works with the above examples? thanks.

Why not post the code here?
I've got no example codes in the device being available and therefore not able to help.
